ABSTRACT

Purpose: To elucidate changes in the neuro?sensory retina at the macula, using spectral?domain optical coherence tomography (SD?OCT) in type 2 diabetics without clinical signs of diabetic retinopathy, and compare with healthy subjects. Methods: This was a cross?sectional observational study, conducted at a tertiary eye institute from November 2018 to March 2020. Type 2 diabetics visiting the outpatient department with normal fundus (without any clinical signs of diabetic retinopathy) were taken as Group 1, and healthy subjects as Group 2. Both underwent recording of visual acuity, intraocular pressure (non?contact tonometry), slit?lamp anterior segment examination, fundus examination using an indirect ophthalmoscope, and macular SD?OCT. SPSS (Statistical Package for Social Sciences) version 20 [IBM SPSS statistics (IBM corp. Armonk, NY, USA released 2011)] was used to perform the statistical analysis of the data entered in the excel sheet. Results: Our study included 440 eyes of 220 subjects, divided equally into two groups. The mean age of patients with diabetes was 58.09 ± 9.42 years, and of controls 57.25 ± 8.91 years. The mean BCVA in group 1 and group 2 was 0.36 ± 0.37 and 0.21 ± 0.24 logMAR, respectively. SD?OCT showed thinning in all areas in group 1 compared to group 2, but statistically significant thinning was seen only in the central subfield (P = 0.0001), temporal parafoveal (P = 0.0001), temporal perifoveal (P = 0.0005), and nasal perifoveal areas (P = 0.023) in group 1. There was a significant inter?eye difference noted between the right and left eyes in nasal and inferior parafovea only in group 1 (P = 0.03). No significant difference was noted between males and females. Conclusion: There was significant macular thinning in diabetics compared with controls, which denotes the occurrence of neuronal damage in these eyes before clinical evidence of diabetic retinopathy.

ABSTRACT

Hypercalcemia is one of the most frequently encountered problems in endocrinology OPD. Although the evaluation may not always be straightforward in all scenarios. Common factors affecting calcium levels such as dehydration, improper sample collection, and vitamin D supplementation may mask a serious underlying disorder. Here, we discuss a case of an elderly female who had symptoms of myelopathy and hypercalcemia whose etiology was initially attributed to excessive sup

ABSTRACT

ABSTRACT Objective: To assess the awareness about COVID-19 among dental patients and determine the association between COVID-19 awareness and perceived stress among dental patients. Material and Methods: A selfadministered knowledge, attitude and practices (KAP) questionnaire and perceived stress scale (PSS) were employed to assess the knowledge and attitude among dental patients visiting the outpatient department. A p-value of ≤ 0.05 was considered statistically significant. An independent t-test was used to compare the KAP and PSS scores based on age, gender, occupation and the responses to unscorable questions. Spearman's correlation was employed to assess the association between KAP and PSS scores. Results: The older participants (mean KAP score = 16±2.2), the participants who answered that the Coronavirus outbreak changed their daily routine (mean KAP score = 15.8±2.2) and the participants who answered that they changed their plans due to the Coronavirus outbreak (mean KAP score = 16±2.14) had significantly higher KAP scores when compared to their respective counterparts. The Spearman's correlation value of -0.45 suggested a moderate negative association between the KAP and PSS scores, but this correlation was not statistically significant. Conclusion: The participants had a moderate to good level of knowledge related to COVID-19 and were positive in their approach and outlook on overcoming the pandemic.

ABSTRACT

ABSTRACT Objective: To study the feasibility of time trade-off (TTO) method in quantifying health utility ratings in different types of malocclusion. Material and Methods: In this cross-sectional study, 70 orthodontic patients aged 18 years or above, reporting for treatment/consultation, were included and interviewed. Malocclusion-related health utilities were assessed through the TTO method, and oral health-related quality of life was measured with the help of Orthognathic Quality of Life Questionnaire (OQLQ). Angle's classification of malocclusion was recorded. Bivariate analyses and multivariate Poisson's regression were done to find out an association between the oral health utility values, OQLQ and demographic and clinical characteristics. Results: Patients with skeletal Class III malocclusion had lower health utility values than those with Class I and Class II malocclusions (p=0.013). Poisson's regression showed that Angle's Class II division 1 (0.90, CI 0.84 to 0.97), Class III (0.68, CI 0.59 to 0.95) and Skeletal malocclusion (0.79, CI 0.71 to 0.87) and OQLQ scores (1.0, CI 1 to 1.003) were found to be significant predictors of TTO utility scores. Conclusions: TTO utilities were found to be valid and well correlated with clinical findings. Health utilities could serve as useful and reliable markers of health-related quality of life (HRQL) among individuals or communities and help cost-effective preventive or intervention programs planning.


RESUMO Objetivo: Estudar a viabilidade do método Time trade-off (TTO) para quantificar escores de valoração da saúde em diferentes tipos de má oclusão. Material e Métodos: Neste estudo transversal, foram incluídos e entrevistados 70 pacientes ortodônticos com idade igual ou superior a 18 anos, que compareceram para tratamento/consulta. A valoração da saúde em relação à má oclusão foi avaliada por meio do método TTO e a qualidade de vida relacionada à saúde bucal foi medida com a ajuda do Questionário de Qualidade de Vida Ortognática (Orthognathic Quality of Life Questionnaire, OQLQ). A classificação da má oclusão segundo Angle foi registrada, e análises bivariadas e regressão multivariada de Poisson foram feitas para verificar qualquer associação entre os escores de valoração da saúde bucal, OQLQ e características demográficas e clínicas. Resultados: Os pacientes com má oclusão esquelética de Classe III apresentaram escores de valoração da saúde mais baixos do que aqueles com má oclusão de Classe I e Classe II (p=0,013). A regressão de Poisson mostrou que a Classe II de Angle divisão 1 (0,90, IC 0,84 a 0,97), Classe III (0,68, IC 0,59 a 0,95), má oclusão esquelética (0,79, IC 0,71 a 0,87) e os escores do OQLQ (1,0, IC 1 a 1,003) foram considerados preditores significativos dos escores de valoração pelo método TTO. Conclusões: Os escores do TTO foram considerados válidos e bem correlacionados com os achados clínicos, e podem servir como marcadores úteis e confiáveis da qualidade de vida relacionada à saúde (health-related quality of life, HRQL) entre indivíduos ou comunidades, e ajudar no planejamento de programas de prevenção ou de intervenção, com uma boa relação custo-benefício.

ABSTRACT

Aim: Bimaxillary protrusion is a common condition observed irrespective of race and ethnicity and is a chief concern for patients who seek orthodontic treatment. The aim of this study was to compare and evaluate changes in soft tissue structures and incisor positions in class I bimaxillary protrusion subjects undergoing orthodontic therapy when friction and frictionless mechanics were used. Methods: Two groups with a total of 40 patients aged 18­30 years diagnosed with class I bimaxillary protrusion treated by extracting first premolars were considered for this study. Patients treated with friction mechanics were included in Group 1 and those treated with frictionless mechanics in Group 2. The digital lateral cephalograms were calibrated and analyzed using Nemoceph software. Selected landmarks were marked on pre- and post-treatment cephalograms and assessed for intra- and inter-group soft tissue and incisor position changes. Student's t-test was used to analyze the collected data using SPSS 20 software. Result: Intragroup comparison revealed significant changes in both groups. Inter-group comparison of the selected parameters between groups 1 and 2 showed differences but without any statistical significance, except for the inter-incisal angle. Conclusion: Pre- and post-treatment comparison analysis revealed significant soft tissue changes in both groups. However, the comparison between friction and frictionless mechanics showed no statistically significant changes

ABSTRACT

Background: Urinary tract infection is a common infection among both genders there was higher prevalence among women probably due to the physiology of urinary tract in women. In addition, age is an important factor where elderly people with urinary devices like catheters are prone to the infection. Aims and Objectives: Study conducted to assess the clinical profile, predisposing factors, uropathogen profile causing Urinary tract infection in elderly women and to identify associated factors responsible for it. Methods: The study was conducted in, S Nijalingappa Medical College and HSK Hospital, Bagalkot, Karnataka and was conducted in the Department of Internal Medicine. Study period extended from December 2018 to May 2020. It was a study on elderly women patients (age>60 yr) with symptoms of UTI admitted in HSK hospital. Patients were selected based on inclusion and exclusion criteria. Total number of 65 patients were taken for the study. Results: In our study, UTI commonly witnessed in the age group was 60-69 years. Most common causative organism is E. Coli isolated in 47.7% cases. The average length of hospitalization was 8.65 ± 8.94 days. Most organisms are sensitive to Nitrofurantoin (43%). Conclusion: 1. Urinary tract infection is common infection among both genders there was higher prevalence among women, age is an important factor where elderly people with urinary devices like catheters are prone to the infection. 2. Diabetes enhances the incidence due to elevated blood sugar levels and has a significant role in the incidence of the infection. 3. As gram negative isolates shows drug resistance, prompt diagnosis and the right choice of antimicrobials can play a key role in reducing mortality in elderly UTI patients.

ABSTRACT

A 17-year-old underweight boy came with a classical emergency of diabetic ketoacidosis associated with two additional clinical features; persistently low blood pressure despite adequate fluid resuscitation and hypogonadal features with Tanner stage 3 pubic hair, absent facial, and axillary hair along with a high-pitched voice. These findings triggered an endocrine workup which revealed hypogonadotropic hypogonadism. Suspecting primary pituitary pathology, an magnetic resonance imaging brain, was done which showed a well-defined hyperintense lesion in the pituitary suggestive of pituitary apoplexy. In the absence of headache, diplopia, and visual field defects, this incidental finding posed a dilemma regarding the diagnosis and management of diabetic ketoacidosis in the presence of apoplexy.

ABSTRACT

Objectives: The aim of the study was to assess the effect of life course factors on dental fear among adult dental patients attending out?reach clinics in a rural area of South India. The objectives were to measure dental fear and changes in socio?economic status during the life course among the study population and to know whether social mobility reduced/increased dental fear. Methods: Dental fear scale and life course data were collected from 403 respondents. The improvement status of individual life course criteria was categorised into “less/minimal”, “stable”, or “upwardly mobile”. Results: The odds of dental fear in the group showing less or minimal upward social mobility was two times that of the stable group [p = 0.022; 95% confidence interval (C.I): 1.104–3.598], whereas the odds of dental fear in the group showing more or good upward social mobility were 4.5 times that of the stable group [p = 0.001; 95% C.I: 1.928–10.515] when adjusted for covariates, that is, participant age, gender, and education and past history of dental avoidance. Conclusion: Social mobility was found to be a risk indicator for dental fear. Dental services may have been affected even with increased standards of living because of psychological factors such as dental fear.

ABSTRACT

Background: Aim of the study was to compare the response of altered fractionation schedule with concurrent chemo-radiation in patients with primary and the nodal disease.Methods: Total of 40 patients (20 in each arm) with stage 1- 4 squamous cell carcinoma of the head and neck with a performance status of 0-2 (ECOG) were included in the study. Arm A was altered fractionation schedule where in patients received 6 fractions per week to a total dose of 6600 cGy in 33 fractions. In Arm B, patients received conventional radiotherapy with concurrent chemotherapy three weekly Inj. of cisplatin (100 mg/m2). Patients were evaluated for acute toxicity every week using the Acute Radiation Morbidity Scoring Criteria. The response was assessed after 6 weeks and 12 weeks post treatment using the RECIST criteria. Data was statistically analyzed.Results: Seventeen patients in Arm A and 18 patients in Arm B completed the treatment. At the end of three months, In Arm A, 7 patients had complete response and in Arm B, 9 patients had complete response of the primary (p>0.05).  When the complete nodal response was compared in both the arms, there was no difference (2 vs 4 in Arm A vs Arm B resp.). But there were more partial nodal responders in Arm B (p = 0.016). The acute toxicities were comparable in both the arms.Conclusions: Altered fraction radiotherapy can be used in early lesions with minimal nodal burden but with locally advanced disease or large nodal burden addition of chemotherapy should not be avoided.

ABSTRACT

Early diagnosis and treatment of acute appendicitis prevents development of markers that have been used to improve the diagnostic accuracy in appendicitis. The objective of this study was to assess the role of procalcitonin in the prediction of complications of appendicitis. METHODSA cross sectional study involving 110 patients diagnosed with acute appendicitis was conducted. After obtaining ethical clearance, informed written consent was obtained from the patients. Blood investigations such as total leucocyte counts, C reactive proteins and procalcitonin levels were done. Cases were categorized into uncomplicated appendicitis (n=67) and complicated appendicitis (n=43). Descriptive analysis, ROC analysis of predictive validity, and Shapiro Wilk test comparing all the three parameters in both the groups was done using IBM SPSS version 22. RESULTSThe mean age was 29.59 ± 9.17 years. 67 (60.91%) had uncomplicated appendicitis and 43 (39.09%) had complicated appendicitis. The WBC, hsCRP, serum procalcitonin percentile had good predictive validity in predicting score as indicated by the area under the curve (0.822). Serum procalcitonin value had a sensitivity of 97.67% in predicting the type of appendicitis and specificity of 94.03%. CONCLUSIONSSerum procalcitonin is a better biomarker than total leucocyte count and hs-C reactive protein in predicting complications of appendicitis and differentiating it from uncomplicated appendicitis.

ABSTRACT

Background: Langerhans cell histiocytosis (LCH) comprises a diverse group of disorders where pathologic Langerhans cells accumulate in a variety of organs. Aims and objectives of the study is to analyse the clinical manifestations and treatment outcomes of patients diagnosed with LCH in a tertiary cancer hospital in South India.Methods: Retrospective analysis of the case records of patients presenting with histological proven case of LCH over a period of 7 years from 2011 to 2018, being treated at Vydehi Institute of Medical Sciences and Research Centre.Results: 10 patients with biopsy proven LCH were included. The median age of diagnosis was 8 years (range 1 to 73 years) and 3 patients aged 18 years or older at the time of diagnosis. The male: female ratio was 3:2. Multisystem involvement was found in 4 patients (40%) and Single system Involvement in remaining 6 patients. Isolated bone lesions were found in 4 patients (40%), 1 patient had isolated Lymph node involvement; 1 patient had oral cavity lesion. None of the 4 patients with multisystem diseases had skin/mucosal involvement; 3 had bony involvement, 2 patients had lung involvement. One patients with multisystem disease expired while 5 patients were lost to follow-up. 4 out of the 10 patients are on regular follow-up and are in remission.Conclusions: Despite limitation by the retrospective nature, this descriptive study was done to provide further disease information regarding Indian population. Data from this study clearly confirms the known fact that most of the patients with Single System LCH have a very good response rate. Patients with multisystem disease have the highest risk of disease related mortality and morbidity as one among the 4 patients with multisystem disease died just after initiating treatment.

ABSTRACT

Background: Microalbuminuria is a marker of endothelial dysfunction and an important risk factor for cardiovascular diseases. Microalbuminuria may be seen due to hypoxemia in patients with chronic obstructive pulmonary disease (COPD). The objectives were to study the presence of microalbuminuria in patients with chronic obstructive pulmonary disease and to determine the relationship of microalbuminuria with severity of COPD using GOLD staging.Methods: The study was done on 68 patients of COPD. Urine spot albumin measurement, pulmonary function tests, spirometry and GOLD staging were done. Severity of COPD was assessed by GOLD staging. Pearson Co-relation test and ANOVA test were used for statistical analysis.Results: Statistical analysis showed that strong and statistically significant positive correlation of Microalbuminuria with GOLD staging(r =0.749, p = 0.001).Conclusions: Microalbuminuria(MAB) was found to increase in patients with increasing severity of COPD. Hence its potential role as a marker of severity of disease and in predicting risk of cardiovascular disease can be explored.

ABSTRACT

Abstract Objective: To assess the total sugar content, endogenous pH, total soluble solids content (TSSC) and titratable acidity of the commonly prescribed long-term and short-term liquid oral medicines (LOM) for children and to compare the erosive potential with the total sugar content and total soluble solids of the LOM. Material and Methods: Twenty-three most commonly prescribed pediatric LOM were evaluated in-vitro for the cariogenic and erosive potential. Manufacturers' information on labels, endogenous pH, titratable acidity, TSSC, and the total sugar content was determined. Descriptive statistics and the Mann-Whitney U test were applied. Results: Overall, 22 LOM contained sugar. Only 3 LOM revealed the sugar content of the formulation but did not disclose the quantity (Cheston, Ventorlin and Eptoin). None of the samples revealed the sugar content as well as endogenous pH in their labels. The overall mean total sugar content was 6.92 ± 3.49 g/100ml, ranging from 3.40 ± 0.00 (corticosteroids) to 9.67 ± 0.61 (antitussive/expectorant). The mean endogenous pH for the total sample of medicines was 5.91 ± 1.51 (range of 3.5 to 10.3). Eptoin (0.013%) presented the lowest titratable acidity and Imol (1.171%) presented the highest titratable acidity with an overall mean of 0.40 ± 0.73. Omnacortil and Epilex presented the highest TSS content (19.3%), and Ventorlin presented the lowest TSS content (18.7%) with an overall mean of 18.97 ± 0.19. Over twelve medicines were identified to have the potential to cause dental erosion. No significant differences were seen in the total sugar content, total soluble solids, titratable acidity, and the endogenous pH between the short-term and long-term LOMs (p=0.145, p=0.263, p=0.067 and p=0.107), respectively. Conclusion: The pediatric LOMs showed the presence of the sugar, low endogenous pH, high titratable acidity and high total soluble solids.

ABSTRACT

Background: The presence of second synchronous or metachronous primary malignancies in a cancer patient is not a rare phenomenon. Our study is an endeavour to present data on the frequency, types, and outcomes of double primary malignancies in Indian cancer patients.Methods: This was a retrospective study conducted in 28 cancer patients diagnosed with histologically confirmed double malignancy. Retrospective data of the cancer site, patient’s age at the presentation, gender, type of cancer (synchronous/metachronous), treatment, and outcome were recorded from patients presented with double malignancies from January 2012 to January 2019.Results: Among 28 patients (18 females; 10 males) with multiple primary malignancies, 10 (35.7%) and 18 patients (64.3%), respectively, had synchronous and metachronous primary malignancies. Overall, breast, gynecological, head, and neck cancer were the most common primary malignancies. Gastrointestinal tract, breast, and lung cancer emerged to be the most common second primary malignancy sites. Squamous cell carcinoma (SCC) and invasive ductal carcinoma (IDC) were the most common histopathological types of double malignancies. The majority of the patients received appropriate treatment for both the malignancies.Conclusions: Data from the present study clearly suggest that the occurrence of second primary malignancy is not rare in Indian cancer patients. The double malignancies can occur at any stage and for any type of cancer. Hence, we wish to highlight that the clinician should always be aware of the possibility of developing second malignancy either during evaluation or in follow up of a patient with malignancy.

ABSTRACT

Background: Anaemia is a very common complication in cancer patients. Up to 60% of solid tumor patients and 70-90% of patients receiving myelosuppressive chemotherapy have anaemia. Pathophysiology of anaemia in cancer patients is multifactorial. The treatments for cancer related anaemia include Erythropoietin Stimulating Agents (ESAs), iron supplementing therapies (intravenous iron, oral iron) and blood transfusion. There are various safety concerns regarding usage of ESAs; also, their usage is less in India due to cost factor. There is scant literature regarding blood transfusion practices in patients undergoing chemotherapy.Methods: Patients diagnosed with cancer and patients receiving chemotherapy were included in the study. Retrospective case record review of cancer patients who received chemotherapy between January to March 2019 was done. Type of malignancy, presence of symptoms related to anemia and trigger for packed red cell transfusion were recorded.Results: Among 342 patients received total of 1365 cycles of chemotherapy in this time period. Mean age of patients was 46 years. 46 of the 342 patients received blood transfusion. Only 13% of the patients had symptoms of anemia like weakness and fatigue the average hemoglobin level at which transfusion was given was 6 gm/dL.Conclusions: Packed Red blood cell transfusion was usually administered at Hb <7 gm/dL. Very few patients reported anaemia related symptoms prior to transfusion. No patient received erythropoietin. Further data is needed from other tertiary cancer centres to understand the blood transfusion practices in Indian cancer patients undergoing chemotherapy.

ABSTRACT

Background: Iodine deficiency disorders (IDD) constitute the single largest cause of preventable brain damage worldwide leading to learning disabilities and psychomotor impairment. Nearly 266 million school children worldwide have insufficient iodine intake. IDD was found to be a public health problem in 47 countries. Since the information on current prevalence of goiter in Kolar was not available, the present study was undertaken.Methods: A cross-sectional study was conducted among school children aged 6-12 years in Kolar taluk. A total of 650 children (325 urban and 325 rural) were selected for goiter examination by multistage random cluster sampling technique. A total of 150 children were tested for the median urinary concentration and 150 salt samples were tested from the households of the study population.Results: The total goiter rate was 6.6% among primary school children aged 6-12 years with a significant difference between ages. As the age increased the goiter prevalence also increased. The median urinary iodine excretion level was found to be 137 µg/l and 92.7% salt samples had >15 ppm iodine content.Conclusions: Present study shows mild goiter prevalence in primary school children in Kolar and an adequate iodine content of salt and urine.

ABSTRACT

Background: It has been possible to set up special newborn care units (SNCUs) and to improve the survival of newborns in India. However, several challenges remain affecting their effective functioning. Different approaches have been attempted and several policies have also been implemented to address this issue. Objectives: To evaluate the feasibility of implementing best practices in neonatal care by onsite mentoring in an SNCU over 4 months. Methods: The mentoring team was from a tertiary care hospital in Karnataka. The SNCU was functioning at the district hospital, catering to approximately 3500 live births per year. Onsite mentoring was carried out from August 2016 to November 2016. This was a prospective implementation research. Framework focused on infection control, preterm care, care at birth, advocacy for infrastructure and resources, and facility-based refresher training. Results: A total of 16 visits were done by the mentoring team and 2 weeks of in-house residency. There were improvements in hand hygiene compliance from 0% to 87.5%, in cleaner IV site (from 50% to 100%), decreased unnecessary oxygen administration (from 75% to 33.3%), decreased antibiotic usage (from 70.5% to 35.5%), decrease in the number of babies receiving >5 days of antibiotics (from 41.6% to 0%), and increased kangaroo mother care initiation rate from 0% to 41.6%. The facility got level IIA accreditation by the end of the intervention period. Conclusions: Onsite mentorship program of SNCU is feasible and planning should be contextual. With the problems being uniform across most facilities, the model could be replicated across the country.

ABSTRACT

Aim: The present investigation was conducted to approximate the magnitude of genotype × environment interaction effects in mungbean crop and to identify suitable genotypes for northern hilly terrain of India. Methodology: Thirty one promising mungbean genotypes were evaluated in three diverse environments, viz., Srinagar, Berthin and Imphal of northern hilly terrains of India. The individual genotype was planted in 5 rows of 4m length in 3 replications in randomized block design. The statistical analysis was done for Additive Main effect and Multiplicative Interaction (AMMI) and genotype main effect plus genotype-by-environment interaction (GGE) biplots analysis. Results: ANOVA devised that the genotypes, environment and genotype × environment interactions were significant for grain yield. The first two principal components, PC1 and PC2 described 73.65 and 26.35 percent variations, respectively, of total variation. According to AMMI I, the genotypes such as Pant M 6, RMG 1092, TMB 134, CoGG 13-19, KM 2349, DGG-8, TRCM 87-6-2-1, KM 2241 and MDGGv-16 were highly stable genotypes. GGE biplot analysis revealed that Pant M 6 and TMB 134 as winning genotypes for Berthin while NMK 15-12 and MDGGV-16 were the best genotypes for Srinagar. The genotypes IPM 14-7 and GAM 5 were found best for Imphal. Overall, high yield and most stable genotype was DGG-8 for northern hilly terrains of India. Interpretation: GGE biplot and AMMI approach could be instrumental in appraising the genotypes performance in multi-environments/locations testing for efficient selection of the stable genotypes.

ABSTRACT

Background: Anthracycline is one of the commonly used chemotherapeutic agents in the treatment of malignancies and their efficacy is undermined by potential life-threatening cardiotoxicity.  The aim of this study is to compare the cardiotoxicity in patients receiving standard short infusion (15-30 minutes) versus prolonged infusion (6 hours) of doxorubicin in the study group.Methods: In this study 80 patients who were planned for treatment with Doxorubicin >200 mg/m2 were included in this study and they were randomly allotted to either of the treatment group. Each patient was assessed clinically (History, Pulse rate, Blood pressure) along with ECG ,ECHO prior to initiation of chemotherapy, after completion of 200 mg/m2 of Doxorubicin, 3 months and 6 months after chemotherapy.Results: There were 40 patients in each group, and they received a total of 384 cycles of Doxorubicin containing regimens according to respective protocols. The median number of cycles was four (range four to six cycles). The mean cumulative dose of doxorubicin was 271.5 mg/m2 in the group which received standard short infusion and 264 mg/m2 in the group which received the drug by prolonged infusion. However, none of the patients developed any cardiac symptoms during or after the planned chemotherapy nor was there a drop in ejection fraction on serial ECHO.Conclusions: There was no benefit of prolonged infusion of doxorubicin as compared to the standard rapid infusion in terms of doxorubicin induced cardiotoxicity. At present, standard rapid infusion is the best option.
